Triglycerides are stored variously throughout the body. The primary storage in in adipose cells. But, of course, there is some stored in intramuscular tissue. The biochemistry of fatty acid metabolism is the same no matter the storage site. Ultimately the fatty acid must be carried into the target cell–muscle cell, myocardial cell, nerve cell (brain)–to enter into the mitochondrial TCA (Krebs) cycle metabolic chemistry to produce ATP.
